Q2. What is principle of transformer
Ans. 
The principle of a transformer is based on Faraday's law of electromagnetic induction.
• Transformers work on the principle of mutual induction between two coils to transfer electrical energy from one circuit to another.

• When an alternating current flows through the primary coil, it creates a changing magnetic field which induces a voltage in the secondary coil.

• The ratio of the number of turns in the primary coil to the nu...read more

Q1. What's resisotr what are the types of transformers
Ans. 
A resistor is an electrical component that resists the flow of electrical current. Types of transformers include step-up, step-down, isolation, and autotransformers.
• Resistors are used to limit current flow in a circuit

• Types of transformers include step-up transformers, which increase voltage, and step-down transformers, which decrease voltage

• Isolation transformers are used to isolate a circuit from the power source

• Auto...read more

Q1. What is chromatography
Ans. 
Chromatography is a technique used to separate and analyze mixtures of chemicals based on their properties.
• Chromatography involves passing a mixture through a stationary phase, which separates the components based on their interactions with the stationary phase and mobile phase.

• Different types of chromatography include gas chromatography, liquid chromatography, and thin-layer chromatography.

• It is commonly used in chemi...read more
